    A few weeks ago my classmates & I stayed at school until 4pm. We set up a projector in class and we were watching your lessons. Thank you so much Mr Nkosi 🙏🥰✨ I also introduced students from other schools in my area to your channel. 😄

    do the original parabola and it’s inverse have to intersect?
    after drawing mine, they only intersect at the origin. is that ok or did i make a mistake?

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว

      The don’t intersect all the time. It’s possible to have them not intersecting

  • @jessicamokhethi2374
    @jessicamokhethi2374 2 ปีที่แล้ว +1

    I have a question with the inverse parabola (x=2y²). When you started on functions you said a graph that has 2 y values for 1 x value doesn't count as a function, so then how does this one work? Or inverses

    • @jessicamokhethi2374
      @jessicamokhethi2374 2 ปีที่แล้ว +1

      Are exceptions to that rule?

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว +1

      An inverse of the parabola is not a function for that reason
